Abstract Apple bitter rot caused by Colletotrichum species is a growing problem worldwide. spp. are economically important but taxonomically un-resolved. Identification of critical due to potential species-level differences in pathogenicity-related characteristics. A 400-isolate collection from New York apple orchards were morphologically assorted two groups, C. acutatum complex ( CASC ) and gloeosporioides CGSC ). sub-sample 44 representative isolates, spanning the geographical distribution...
Colletotrichum fioriniae of the C. acutatum species complex is an important hemibiotrophic pathogen vegetables and fruits in temperate regions worldwide. In apple, it one primary responsible for bitter rot disease. Understanding disease cycle complicated because many broadleaf plants can be hosts fioriniae. By detecting quantifying rain-splashed conidia more than 500 samples from heavily bitter-rot-infected apple orchards nearby forested woodlots over two summers, we show that conidial...
Apple growers in the Mid-Atlantic region of United States have been reporting an increase losses to bitter rot apple and are requesting up-to-date management recommendations. Management is complicated by variations cultivar susceptibility, temperature, rainfall, biology Colletotrichum spp. that cause rot. Over 500 fruit with were obtained from 38 orchards across causal species identified as fioriniae C. nymphaeae acutatum complex chrysophilum, noveboracense, siamense, fructicola, henanense,...
Managed colonies of European honey bees (Apis mellifera) are under threat from Varroa destructor mite infestation and infection with viruses vectored by mites. In particular, deformed wing virus (DWV) is a common viral pathogen infecting worldwide that has been shown to induce behavioral changes including precocious foraging reduced associative learning. We investigated how DWV affects the transcriptomic response brain. The transcriptomes individual brains were analyzed using RNA-Seq after...
Apple orchards with minimal or reduced fungicide inputs in the Mid-Atlantic region of United States have experienced outbreaks severe premature defoliation symptoms that matched those apple blotch disease (ABD) caused by Diplocarpon coronariae. Fungal isolates obtained from symptomatic leaves and fruit produced uniform slow-growing, dark-gray colonies on peptone potato dextrose agar had conidia. Internal transcribed spacer DNA sequences D. coronariae Koch's postulates were fulfilled when...
Apple growers in the Mid-Atlantic region of U.S.A. have reported increased losses to bitter rot apple. We tested hypothesis that this increase is because Colletotrichum population has developed resistance commonly used single-mode-of-action (single-MoA) fungicides. screened 220 isolates obtained from 38 apple orchards for 11 fungicides Fungicide Resistance Action Committee (FRAC) groups 1, 7, 9, 11, 12, and 29. Eleven (5%) these were resistant FRAC group 1 with confirmed β-tubulin E198A...
Bitter rot is a major disease of apple fruit in warm and humid regions. It caused by various species the Colletotrichum gloeosporioides C. acutatum complexes, which fioriniae complex most common Mid-Atlantic region United States. While bitter management begins with good cultural practices, fungicides are generally used for consistent control. Fungicides should be applied before or during infection periods, but timing unclear due to hemibiotrophic lifestyle causal species. To determine when...
Background: Metabolomics offers the potential of correlating a macroscopic view an organism to measured levels small molecule reporters metabolic pathways. Despite strong growth in metabolomics studies, questions on reproducibility and sample stability deserve closer look. Keywords: Metabolomics, metabonomics, NMR, profiling, reproducibility, stability, serum.
The feasibility of metabolomic 1H NMR spectroscopy is demonstrated for its potential to help unravel the complex factors that are impacting honeybee health and behavior. Targeted non-targeted metabolic profiles liquid tissue samples organisms could provide information on pathology infections environmentally induced stresses. This work reports establishing extraction methods characterization Apis mellifera, European honeybee, describes currently assignable aqueous metabolome, gives examples...
In this work, we aim to accelerate diffusion weighted MRI (dMRI) by predicting -weighted images (DWIs) across different shells using deep learning (DL), while remaining independent of a diffusion-model constraint. The proposed approach enables the predictions unacquired DWIs in multiple from small set acquired given shell. This relaxes need for applying gradient weightings obtaining fully-acquired dataset over shells. Without constraint model, accurate metrics models can potentially be...

Bitter rot is a disease of apple caused by fungi in the genus Colletotrichum. Management begins with removal infected twigs and fruit from tree canopies to reduce overwintering inoculum. Infected are usually tossed orchard floor, which generally managed as herbicide-treated weed-free rows, separated grass drive rows. We monitored decay rates succession bitter canopies, on soil surface nearby diverse plant communities. hypothesized that would occur most rapidly within communities, provide...
Seven Isolates of Colletotrichum acutatum have been collected from strawberries attacked with anthracnose in the Loukous territory, Morocco. The study effect vitro 3 fungicides Thiram as active substance and another one copper on seven isolates C. was studied. has a potent effectiveness germination is moderately effective mycelial growth sporulation.

The aim of this work is to investigate the used Transformer architectures in radial image reconstruction. While most deep-learning reconstruction methods are based on convolutional neural networks (CNNs), recent advances computer vision suggest that architecture may provide a favorable alternative many tasks. In work, we demonstrate can be for sinogram interpolation and yield results comparable CNNs.
